615: Update default Monero node URLs and info r=thomaseizinger a=da-kami
xmr.to nodes are not served at the xmr.to domain but moved to melo.tools

The Rust compiler doesn't guarantee in which order field initialization
are executed. By extracting them, we can make sure they run in a certain
order. This will be important as we add more validations that can
fail.
For builds made directly on the tag, the output of `--version` will
not change. For builds not made on a tagged commit, the output will
look something like this:
```
> swap --version
swap 0.7.0-117-g93161f9
```
Fixes#409.
We emit an `info!` log for every peer that we discover but only ever
emitted a `debug!` log if we fail to connect. This leads to a situation
where the user would run `swap list-sellers`, the logs would say
"Discovered XYZ at ABC" but then get a potentially empty table.
To not confuse the user, we include unreachable nodes in the table output.
For example:
```
Connected to rendezvous point, discovering nodes in 'xmr-btc-swap-testnet' namespace ...
Discovered peer 12D3KooWPZ69DRp4wbGB3wJsxxsg1XW1EVZ2evtVwcARCF3a1nrx at /dns4/ac4hgzmsmekwekjbdl77brufqqbylddugzze4tel6qsnlympgmr46iid.onion/tcp/8765

1. Clearly separate the log messages from any fields that are
captured. The log message itself should be meaningful because it
depends on the underlying formatter, how/if the fields are displayed.
2. Some log messages had very little context, expand that.
3. Wording of errors was inconsistent, hopefully all errors should
now start with `Failed to ...`.
4. Some log messages were duplicated across multiple layers (like opening
the database).
5. Some log messages were split into two where one part is now an `error!`
and the 2nd part is an `info!` on what is happening next.
6. Where appropriate, punctuation has been removed to not interrupt
the reader's flow.
Log statements end up getting changed constantly and having to clean
up imports after that is annoying, for example, if the last `info!`
in a file disappears, you end up with an unused import warning.
Fully qualifying tracing's macros prevents that and also communicates
clearly that we are using tracing and not log.
Sorting `psbt.output` by `witness_script` is at times pointless
because it might be set to `None`. To be more robust, we pattern
match against the produced transaction.
The CLI's transport doesn't support memory addresses and it also shouldn't support those by default. To be able to use it in tests, we extend the `SwarmExt` trait with the ability to listen on local TCP addresses with a random port.
The rendezvous protocol allows us to register all of our external
addresses. Hence, the first step is to allow the user to configure
external addresses as part of the config. In the future, there might
be an automated way of determining these.
To register with a rendezvous node, the user needs to configure which
one. CoBloX is running a rendezvous node that acts as the default by
every spec-compliant node will do the job just fine. This behaviour
is optional which is why our custom behaviour is wrapped in a `Toggle`.
We also want our node to re-register after half the time of the
registration has passed. To make this simpler and allow for testing in
isolation, we create a custom behaviour that wraps the libp2p rendezvous
behaviour.
This command uses a rendezvous node to find sellers (i.e. ASBs) and query them for quotes.
Sellers, that can be dialed and queried for a quote will be listed.
